Description
The CR2025 is a 3V lithium coin cell, and this pack holds two of them. The code is the specification: under the standard naming used across the battery industry, CR marks a lithium chemistry in a round cell, 20 gives the diameter in millimetres and 25 gives the height in tenths of a millimetre. That last figure is the one people get caught out by, because the far more common CR2032 shares the same 20mm width but stands 3.2mm tall. The two are not interchangeable, and the cells here arrive in a child resistant blister the pack marks in English and French.
Flat, low drain electronics are where a CR2025 earns its keep: car key fobs, slimline remote controls, watch and clock movements, calculators, digital thermometers, kitchen scales and the small lights built into novelty cards. Before ordering, take the old cell out and read its face, or check the device manual. The code is printed on the cell itself and it is the only dependable way to match one, since several coin cells look almost identical at a glance. Buying a pair gives you a spare, and a dead key fob is usually noticed at the worst possible moment.
The pack states the cells are ready to use up to 10 years in storage, so a spare pair bought now should still be good when the fob finally dies. Voltage is 3V, printed on the pack and stamped on each cell. Coin cells are a known swallowing hazard for small children, which is why the packaging is child resistant and marked with a scissors symbol; keep any spare in its blister and out of reach. One unit of this listing is one pack of two cells, and the minimum order is 10 packs, so 20 cells in total. It sits alongside our wider range of Eveready cells in AA, AAA, C, D and 9V.

Frequently Asked
Will a CR2025 work where a CR2032 is specified?
No. Both cells are 20mm across, but a CR2032 is 3.2mm thick against 2.5mm here, so the contacts in a deeper holder may never meet. Always match the code printed on the old cell.
How many cells do I actually receive?
Each pack contains two CR2025 cells. The minimum order on this listing is 10 packs, which works out at 20 cells in total.
What voltage do these give?
3V, printed on the pack and stamped on each cell. Lithium coin cells of this type hold their voltage steadily for most of their working life rather than tailing off slowly.
How long can I keep spares before using them?
The pack states the cells are ready to use up to 10 years in storage, so buying ahead and keeping a pair in a drawer is reasonable.
Can these be recharged?
No. Lithium coin cells of this kind are single use, and a primary cell should never be put on a charger. Fit a fresh one and recycle the old cell at a battery collection point.
How do I get the pack open?
The blister is child resistant and carries a scissors symbol, so have a pair to hand rather than trying to tear it by the corner.
